I'm really glad MATE exists, I've been using Linux as my main OS for years now and Gnome 2 is what I started off with and preferred it over KDE, XFCE at the time.
I still prefer to use MATE instead of unity, KDE, XFCE, Gnome 3.
I dont mind XFCE but I'm not a big fan of thunar of pcmanfm.
I'm currently installing LM13 MATE 32bit onto a Dell Latitude D610 ( Intel Pentium M processor 1.86Ghz, 486MB RAM)
very old laptop, no way would i think of installing Gnome 3, KDE or unity on it
